Dakota Johnson and Machine Gun Kelly dating rumors are as hot as the couple themselves … and they added fuel to the fire this week after they left a music studio together.

The actress and the rapper were spotted in Los Angeles earlier this week … Dakota wearing a jacket and pants while waiting for the hoodie-wearing Kelly to finish up a phone call.

Eventually, MGK came around and opened the door of his sports car for DJ … who hopped in the passenger seat. The two then took off for parts unknown.

As we reported … the rumor mill first started churning when they were spotted hanging out last month in New York City — walking into Taylor Swift‘s apartment.

The two allegedly met at Taylor’s wedding to Travis Kelce at Madison Square Garden back in July.

As you know … Dakota and Kelly both have their fair share of famous exes. MGK shares a kid with Megan Fox, while Dakota was previously in a long-term relationship with Chris Martin.
